SW encourages you to fill yourself up with "free foods", which prevents your stomach shrinking and thus prevents you gaining control over your hunger.
With so many definitions of vegetarian it's hard to offer advice without knowing where on the scale you sit. Where do you get your protein from?
Do you drink alcohol? Do you smoke? What're your favourite foods? What do you eat most often?
An excellent calorie calculator is here:
Calorie Calculator - as you lose weight the calories you need will change, so it's best to re-check every time you drop a few pounds.
The calorie calculator will tell you how many to eat to lose 1 or 2lbs per week. 2lbs is the ideal maximum for sustainability and healthy weight loss.
Get your calories from healthy foods where possible - vegetables, fruits, unprocessed goods. Don't panic if you resort to a bag of crisps once in a while, just be sure to factor it in to your daily total. Even a bit of cheese now and then isn't a crisis, so long as you don't eat a whole block of it
Once you've been calorie counting for a few weeks you get a much better steer for what's worth your time eating, and what's not worth it. And as yummy as chocolate is, it just ain't worth it most of the time
